My go-to source for kombucha brewing supplies is Kombucha Brooklyn (see Resources). There are also other sources, although some sell the SCOBY in a dehydrated state. The “live” SCOBY is easier to work with and produces a great batch of kombucha the first time, whereas it can take a few batches with a dehydrated SCOBY for productive brewing.
Before you start brewing your own kombucha, it is important to know that it is a process that takes time. Typically the brewing takes 7 to 14 days, although when you first start it could be 15 to 28 days, depending on brewing conditions and factors like temperature and water quality.
